From 681cd988d3587ca2b3afa3db598a2ecab572b742 Mon Sep 17 00:00:00 2001 From: Luis de Bethencourt Date: Sun, 11 Oct 2015 14:16:57 +0100 Subject: [PATCH] staging: rtl8712: fix negative level value range->avg_qual.level is of type uint8, so it shouldn't be assigned a negative number. Assigning it 0x100 - 78, which is the equivalent to (20 + -98) dBm when IW_QUAL_DBM is set.
